After successfully getting RAID 1 to be bootable on my Fedora 10 setup, I ran the update and one of the things updated was my kernel. It appears that the new kernel was added to the grub/menu.lst for the first HDD, but not for the second. Does this new kernel have to be added to the second HDD manually? Or was my bootable RAID not as successful as I hoped?

But a question still remains: Must I do this each time I have a kernel update? Such updates are fairly frequent for Fedora (and, I suppose. other distros too, since they share the same kernel). I must assume the answer is yes, though it would be nice to somehow automate this. But I'm looking for some reassurance ...

Also, if the new kernel works fine, I don't see any need to keep any more than one previous version of the kernel in the grub menu.lst, correct?

By the way, "cat /proc/mdstat" shows exactly as in your HowTo, which is exactly what I expected.
